This paper reports the modelling and analysis of three dimensional negative dielectrophoretic traps for cell trapping applications. Dielectrophoresis is a well-established technique for cell analysis and cell trapping. Planar electrodes, at the bottom of a microfluidic channel, have been ... 詳細を見る

Interfacial structures/pattern, especially with small-scale dimensions, are important to the chemistry of materials in determining the optical, electrical, mechanical, or other physical properties of novel materials. Polymers are often used for surface patterning. The diversity, the ... 詳細を見る

This paper presents a methodology towards designing, analyzing and optimizing piezoelectric interdigitated microactuators using COMSOL Multiphysics. The models used in this study were based on a circularly interdigitated design that takes advantage of primarily the d{;sub}33 ... 詳細を見る

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the ... 詳細を見る

This poster presents the design and analysis of a novel horseshoe shaped MEMS actuator for adaptive optics. The actuation mechanism is Lorentz force enabling low current (below 10 mA) operation. The actuator combined with an overlying aluminum coated SU-8 soft polymer membrane for the ... 詳細を見る

This paper describes the implementation of an app for calculating low frequency electric fields outside electrical installations. The app is based on a 2D parametric geometry chosen in such a way that it approximates a large class of electrical installations, which consist of a tower or ... 詳細を見る

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... 詳細を見る

Electrospray propulsion is a contemporary type of thruster technology that electrostatically drives particles through an extractor grid without the need of a pump. The basis of this propulsion system is the coalescence of propellant into a Taylor cone and through a charged extraction ... 詳細を見る

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... 詳細を見る
